IMPROVEMENT IN MACHINES FOR FINISHING WIRE CAPS.

Specification forming part of Letters Patent No. 166,076, dated July'27, 1875; application filed May 7, 1875.

CASE B.

To all whom it may concern Be it known that I, ADRIEN DE MESTRE, ofBordeaux France, have invented a certain new and Improved Machine forFinishing Wire Caps, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in whichFigure 1 represents a vertical section. Fig. 2 is a partial side view ona larger scale than the previous figure. Fig.3 is a side view of a wirecap when finished. Fig. 4 is a side view of the cap before the same hasbeen fully finished.

Similar letters indicate corresponding parts.

This invention consists in the combination of a cupshaped die with aconical plunger, the cupshaped die being supported on a springbar sothat it can swivel, and provided on its edge with recesses, while theplunger is also mounted so that it can swivel, and provided with aprojecting edge, whereby the operation of finishing the caps ismaterially facilitated. The hollow die can be depressed by treadle, andthe plunger is provided with a pusherbar, to facilitate the discharge ofthe finished caps from the apparatus.

In the drawing, the letter A designates a wooden table, on which issecured a box, B, for the reception of the wire caps to be finished. Onthis table is fastened a standard, 0, through the end of which extends aplunger, D, through which passes a rod, a, which is forced up by aspring, I). The plunger is feathered to the rod a, and the former isconfined in the standard 0, so that both the plunger and rod can revolvefreely. The lower end of the rod a is formed with a head, 0, and saidrod can be depressed independent of the plunger by means of the lever K.The plunger-D fits a cup-shaped die,

. corresponding in number and position to the branches (2 of the wirecaps to be finished. (See Fig. 4.) The rod F slides freely up and downin a suitable socket in the foot of the standard 0, and it is subjectedto the action I of a spring, f, which has a tendency to force the die Eagainst the plunger D. A treadle, G, which connects with the rod F,serves to depress the same against the action of its spring. The plungerD is provided with a projecting edge, g, which serves to bring the loopsof the caps to be finished in the proper position, so that the same canbe readily applied to the neck of a bottle.

When the die E has been depressed by the treadle Gr, one of the caps tobe finished is placed in the same, its branches 6 being adjust-ed in thenotches d; then the plunger is permitted to ascend, and the cap isfirmly retained inposition between the plunger and the die; but it,together with said plunger and die, can be freely turned round. The endsh of the wire, Fig. 4, are then passed through the loops 6, said loopsbeing made to lie over the projecting edge of the plunger, and by thisoperation the cap is brought in the form shown in Fig.3. The die E isthen depressed, and by pressing on the lever K the finished cap isforced off from the plunger, ready to be applied 'to a bottle.

The invention described in this application for a patent was patented inEngland in 1874,

and is numbered 683.

What I claim as new, and desire to secure by Letters Patent, is

The cup-shaped die E, swiveled upon the spring-impelled bar F, andhaving notches (I, for receiving the wires to form the cap, incombination with the swiveled plunger D, having a projecting edge forbringing the loops of the wire cap into the proper position,substantially as described, and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 24th day of March, 1874.
